Analysis in multi-byte string URL

Hello.
I really appreciate for this very convenient plug-in.

I have some problems using this plug-in for blogs written in Japanese.

Japanese character is muti-byte and there seems to be some problems for
viewing the statistics about the pages written in Japanese.
In case that I set article title strings into permalink URL, there seems
to be something wrong in the function of viewing the statistics doesn’t
work.

Google Analytics is working.
So maybe it is because of muti-byte character, I think.
This plug-in is really good. And I really want to use this for analyzing.
If you solve this problem that will be a big help for Japanese blogs.

Thank you for your consideration.
